After a close contest we are please to annoue that our next winning topic is:

Water is our lifeline that bathes us and feeds us.  Can we minimize useage of water? Can we avoid using plastic in our practice? Are there any alternatives? With the advent of newer tooth bonded restorative materials and various bonding agents and adhesive systems, the use of amalgam as a restorative material has decreased drastically. So chances of mercury contamination have slimmed down. Similarly, can we avoid the use of plastics? Are there any means to use water conservatively or any alternatives to water usage in our field?
